Merl Effect
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
MerlEffect enhances your gameplay by adding an all-new effect called 'merl' that you can inject upon yourself. Upon recieving the effect, all of the text in the game (excluding dynamic text, such as chat messages) will turn into 'I don't know' as shown below:
A Merl potion is brewed using a nether star. When applied, it magically turns your brain into Merl's!
Currently supports 1.21.11. If you would like to request a version, please do so on my Github - I'll get on it right away!
